Are you referring to
It looks focused to me.
Or, did you mean
Focus looks reasonably good there too:
The rule, should you choose to follow it, is the near eye should be in focus. Focus could be slightly further back, possibly an inch or so depending on her facial structure and the distance between the plane her lower lip is in and the one her eye is in. Individual eyelashes are recognizable, and DOF is quite shallow, so it’s far from front page material, and the expression is great! Expression and an interesting photo trump technical details, so it gets my vote as an acceptable picture. Sharper eyes would take some focus off her mouth, where is the focus of this shot? Would a slightly deeper DOF have been a better choice?
Aidan should try charging, to see what her market will bear. People are charging for work that is inferior to hers.
